Note that the shopping cart 10 functions as a registration device thatreads the product code of a product that a shopper desires to purchase.A list of read products is transferred to a separate device, i.e., apayment device (not shown). Assumption is made that the shopper uses thepayment device to which the list of products has been transferred tomake payment.

As shown in FIG. 1, the shopping cart 10 according to this embodimentincludes a cart body 20 and an electrical device 100. The electricaldevice 100 is attached to the cart body 20. The cart body 20 transportsa shopping basket for housing products. The cart body 20 includes acaster part 30, a frame part 40, and a basket reception part 50. Thecaster part 30 causes the cart body 20 to smoothly move on the floorsurface. The frame part 40 is erected on the rear wheel side of thecaster part 30. The basket reception part 50 is attached at theintermediate position in the height direction (vertical direction) ofthe frame part 40 to protrude toward the forward direction of theshopping cart 10. The caster part 30 and the basket reception part 50are configured to be capable of appropriately carrying a shopping basketthereon. Note that in this embodiment, the direction in which the basketreception part 50 projects from the frame part 40 (forward direction ofthe shopping cart 10) is referred to simply as forward or one side ofthe first direction in some cases as shown in the drawings. Further, inthis embodiment, the side of the frame part 40 (rearward direction ofthe shopping cart 10) is referred to simply as rearward or differentside of the first direction in some cases as shown in the drawings.Further, the extending direction of a handle bar 42 described below isreferred to simply as width direction or second direction in some casesas shown in the drawings. The above-mentioned first direction and thesecond direction are, for example, directions orthogonal to each other.Further, the height direction of the shopping cart 10 orthogonal to thehorizontal surface including the forward, the rearward, and the widthdirection of the shopping cart 10 will be referred to simply as verticaldirection in some cases as shown in the drawings.

The caster part 30 will be described in more detail. The caster part 30includes a square frame-shaped frame 31 having a rear side opened, andcasters 32 provided at four corners of the frame 31. The casters 32 eachinclude a bracket 32 a and a wheel 32 b. The bracket 32 a freely rotatesaround an axis in the vertical direction (height direction of theshopping cart 10). The wheel 32 b freely rotates around the horizontalaxis of the bracket 32 a. The wheel 32 b is formed of rubber or a resin.Note that a reception part 33 is provided on the frame 31. The receptionpart 33 is formed in the dimension in which the lower part of theshopping basket is housed. That is, the reception part 33 is configuredto be capable of appropriately carrying another shopping basketdifferent from the basket reception part 50 thereon.

The reception part 33 includes a contact part 34 and a regulation plate35. The contact part 34 is formed at the front end of the reception part33. When the shopping basket is placed on the reception part 33, thecontact part 34 is in contact with the shopping basket to support theshopping basket. The regulation plate 35 is provided rearward of thecontact part 34 in the reception part 33. When a plurality of shoppingcarts 10 is stacked, the regulation plate 35 is in contact with thecontact part 34 of the rearward shopping cart 10 to regulate thedistance between the shopping carts 10. When the plurality of shoppingcarts 10 is stacked, the contact part 34 is in contact with theregulation plate 35 formed on the frame 31 of the forward shopping cart10 to regulate the distance between the shopping carts 10. That is, whenplurality of shopping carts 10 is stacked, the regulation plate 35 has afunction of regulating the distance with the rearward shopping cart 10,and the contact part 34 has a function of regulating the distance withthe forward shopping cart 10. As described above, by regulating thedistance between the shopping carts 10, it is possible to prevent, whenstacking the shopping carts 10, the hand scanners 130, the tablet cases140, scanner holders 160, and the like of the forward and rearwardshopping carts 10 from being interfered with each other.

Note that the stacking means arranging the plurality of shopping carts10 in a line along the front-rear direction. Then, as shown in FIG. 7,it represents pushing the front end side of the shopping cart 10 locatedon the rear side into the rear side of the shopping cart 10 located onthe front side, i.e., the side of the frame part 40 for housing. Theshopping cart 10 includes a flap plate 54 (described below) provided onthe rear side. The flap plate 54 has a structure in which the front endside of the shopping cart 10 located on the rear side is pushed asdescribed above and thus, the flap plate 54 is opened by being pushed uptoward a reception unit 52 (described below). Therefore, even in thecase where the plurality of shopping carts 10 are arranged, it ispossible to shorten the total length along the front-rear direction andimprove the efficiency of housing the shopping cart 10.

As shown in FIG. 1, the frame part 40 includes a pair of vertical frames41 and 41, and the handle bar 42. The vertical frames 41 and 41 areattached on the side of the right and left rear wheels of the casterpart 30. The handle bar 42 extends in the width direction, and connectsthe upper ends (upper end parts in the vertical direction) of thevertical frames 41 and 41. An extension arm 43 is attached to thevertical frame 41 on the left side in FIG. 1.

As shown in FIG. 1, the basket reception part 50 includes a squareframe-shaped frame 51 and the reception unit 52 provided on the lowerside of the frame 51. The reception unit 52 is formed in the dimensionin which the lower part of the shopping basket is housed. The frame 51includes a horizontal frame 53 on the rear side. The flap plate 54 isattached to the horizontal frame 53 so as to freely swing around thehorizontal frame 53.

The electrical device 100 includes a battery 110 and a productregistration device 120. The battery 110 is disposed below the rear endof the basket reception part 50. Specifically, the battery 110 isattached across the vertical frames 41 and 41 in the middle part of theframe part 40. The product registration device 120 is attached to theupper end (upper end portion in the vertical direction) of the extensionarm 43. The battery 110 supplies power to the product registrationdevice 120 via a power line inserted into the extension arm 43. In thisway, the shopping cart 10 operates as a registration device that readsthe product code of a product that a shopper desires to purchase andmoves by being pushed by the shopper.

The product registration device 120 includes the hand scanner(acquisition device) 130 that reads a product code and the tablet case140. A tablet terminal 150 is provided inside the tablet case 140. Onthe surface of the tablet case 140, the scanner holder (holding part)160 that detachably holds the hand scanner 130 is provided.

As shown in FIG. 2, the hand scanner 130 includes a head 131 and ahandle 132 integrally provided to the lower part on the rear side of thehead 131. As shown in FIG. 6, the head 131 includes an informationacquisition unit 131 a that is provided on one side (on the front side)of a first direction and is to be directed to a product in order toacquire product information of the product. The head 131 has apredetermined width (hereinafter, referred to as first predeterminedwidth) in a second direction orthogonal to the above-mentioned firstdirection, and is formed to have the first predetermined width on therear side (on the different side of the first direction) narrower thanthe first predetermined width on the front side (on the one side of thefirst direction). More specifically, the head 131 is narrowed in thelateral direction (width direction) generally from the front side to therear side as viewed from above in the vertical direction. Further, asshown in FIG. 4, the head 131 has such a shape that a central portion iswider in the width direction and an upper part (part on the upper side)and a lower part (part on the lower side) in the height direction(vertical direction) are narrower as viewed from the front (rear side ofthe first direction). Further, as shown in FIG. 2 or FIG. 5, the head131 includes the information acquisition unit 131 a that is provided onthe front side (on the one side of the first direction) and acquires theproduct code (product information) of a product. The informationacquisition unit 131 a is directed to the product to acquire the productcode of the product. For example, as shown in FIG. 2 or FIG. 5, the head131 includes a flat placement part 131 c on the lower side on the frontside. For example, as shown in FIG. 6, the head 131 includes contactparts 131 d on both side surfaces on the rear side. Note that assumptionis made that the maximum dimension in the width direction of the head131 is W (see FIG. 6). Further, assumption is made that the dimension inthe width direction of the head 131 between the contact parts 131 d is T(see FIG. 6).

As shown in FIG. 5, the handle 132 is provided on the lower part on therear side (the different side of the first direction) of the head 131,and has a predetermined width (second predetermined width) in the seconddirection. The handle 132 is formed to have the second predeterminedwidth narrower than the first predetermined width on the rear side (onthe different side of the first direction) of the head 131. Further, thehandle 132 includes a scanner trigger 133. The scanner trigger 133 isprovided on the front side (on the front side of the first direction) ofthe handle 132. The scanner trigger 133 is operated to start the scanneroperation (operation of acquiring product information) by theinformation acquisition unit 131 a. Note that assumption is made thatthe maximum dimension of the handle 132 in the lateral direction (widthdirection) is H (see FIG. 4).

The hand scanner 130 is connected to the tablet terminal 150 via, forexample a curl cord 134 shown in FIG. 2 and a built-in cable 135 shownin FIG. 3. One end of the curl cord 134 is connected to the informationacquisition unit 131 a of the head 131, and the other end thereof isconnected to the built-in cable 135. The built-in cable 135 is housed inthe tablet case 140 described below. The length of the curl cord 134 isset such that the hand scanner 130 does not reach the floor surface evenin the case where the hand scanner 130 hangs on the shopping cart 10 byits own weight when the shopper drops the hand scanner 130. Further, thecurl cord 134 can be extended by the shopper as necessary. For example,the length of the curl cord 134 is set such that the curl cord 134reaches near the bottom surface of the shopping basket placed on thereception part 33 of the caster part 30 farthest from the scanner holder160.

The hand scanner 130 reads the product code attached to a product takenout of a display shelf by the shopper. The product code is a unique codeset for each product for individually identifying the product.

The tablet case 140 is formed in a thin box shape. As shown in FIG. 3,the tablet case 140 includes a case body 141 and the open/close lid 142.The case body 141 is fixed to the extension arm 43. The open/close lid142 is openably/closably attached to the case body 141. The open/closelid 142 includes an opening part 143. As shown in FIG. 5, a front part132 a of the handle 132 of the hand scanner 130 is in contact with alower end edge 144 of the tablet case 140. For example, as shown in FIG.2 or FIG. 4, an attachment part 145 is formed on the front surface ofthe tablet case 140. For example, as shown in FIG. 2 or FIG. 5, in thetablet case 140, a stopper (handle contact part) 146 is formed at thelower end edge 144 of the case body 141. The stopper 146 is in contactwith the handle 132 of the hand scanner 130 while the hand scanner 130is held by the scanner holder 160 to regulate the forward movement ofthe handle 132.

As shown in FIG. 3, the tablet terminal 150 includes a terminal casing151. The terminal casing 151 is disposed close to the right side in thewidth direction of the case body 141 in FIG. 3. The terminal casing 151includes a display panel 152. The display panel 152 displays varioustypes of information such as the product name and the unit price of theproduct read by the hand scanner 130. The display panel 152 is disposedto face the opening part 143 of the tablet case 140. The display panel152 is exposed to the outside through the opening part 143 of the tabletcase 140. In FIG. 3, a terminal part 153 is provided on the left sidesurface in the width direction of the terminal casing 151. A controller154 is provided inside the terminal casing 151. The controller 154collectively controls the battery 110, the hand scanner 130, and thetablet terminal 150. The controller 154 acquires product information onthe basis of the product code read by the hand scanner 130.

As shown in FIG. 2, the scanner holder 160 is provided on the terminalcasing 151 of the tablet terminal 150. The scanner holder 160 includes ahead support 161 and a pair of head regulators 162, and holds the handscanner 130 in cooperation with the stopper 146 of the tablet case 140.Specifically, the scanner holder 160 that holds the hand scanner 130includes the stopper 146. The head support 161 is attached to theattachment part 145 of the tablet case 140. The placement part 131 c ofthe head 131 is placed on the head support 161. The pair of headregulators 162 are provided to have a space described below. The headregulators 162 are engaged with a rear end side part 131 b of the head131 to hold the head 131.

The head support 161 is formed by bending a plate-like member. Forexample, as shown in FIG. 2 or FIG. 5, the head support 161 includes aretaining part 161 a, an extending part 161 b, and a supporting part 161c. The retaining part 161 a is attached to the attachment part 145. Theextending part 161 b extends in a direction away from the attachmentpart 145 from the upper end (upper end part) in the vertical directionof the retaining part 161 a. The supporting part 161 c is folded back tothe side of the attachment part 145 from the extending part 161 b. Thesupporting part 161 c is formed to have a horizontal surface or asurface having the rear part slightly higher than the front part. Thesupporting part 161 c makes surface contract with the placement part 131c of the head 131.

The head regulators 162 are provided to have a space that is narrowerthan a maximum width W (see FIG. 6) of the first predetermined width ofthe head 131 and wider than a maximum width H (see FIG. 4 and FIG. 6) ofthe second predetermined width of the above-mentioned handle. The headregulators 162 are in contact with the side surface (rear end sidepart131 b) on the rear side (on the different side of the firstdirection) of the above-mentioned head 131 held in the space to regulatethe rearward movement. More specifically, for example, as shown in FIG.2 or FIG. 5, the head regulators 162 includes a pair of arms 163. Thepair of arms 163 are attached to the supporting part 161 c at the baseend thereof. The arms 163 each include a base-end arm 163 a, ahorizontal arm 163 b, and a regulation arm 163 c. The base-end arm 163 ais on the side of the base end of the arms 163, and is formed to extendin the upward direction (upward direction of the substantially verticaldirection). The lower end (lower end part in the vertical direction) ofthe base-end arm 163 a is attached to, for example, the supporting part161 c of the head support 161. The horizontal arm 163 b is formed toextend in the horizontal direction from the upper end of the base-endarm 163 a (upper end part in the vertical direction in the figure). Theregulation arm 163 c is formed to extend in the downward direction(downward direction of the vertical direction in the figure) from thefront end side of the horizontal arm 163 b. A member that applies africtional force to the head 131 is attached to the regulation arm 163c. More specifically, as the above-mentioned member that applies thefrictional force, rubber tubes 164 that are non-slips for the contactparts 131 d of the head 131 are attached to the regulation arm 163 c.The rubber tubes 164 each have a predetermined length R in the verticaldirection in the figure (see FIG. 4).

For example, as shown in FIG. 2 and FIG. 6, the pair of horizontal arm163 b are disposed along the shape of the head 131 so that the distancebetween them is reduced as they away from the attachment part 145 of thetablet case 140. Further, a dimension Q of the distance (distance in thewidth direction in FIG. 4) between the pair of rubber tubes 164described above is substantially the same as a width dimension T (seeFIG. 6) between the contact parts 131 d of the head 131 described above.Further, the dimension Q of the distance between the rubber tubes 164 isset to be narrower than the maximum width W (see FIG. 6) in the widthdirection of the head 131 and wider than the maximum width H (see FIG. 4or FIG. 6) in the lateral direction of the handle 132.

Therefore, when the placement part 131 c of the head 131 is placed onthe supporting part 161 c of the scanner holder 160 while theinformation acquisition unit 131 a of the tablet case 140 is directedforward, the contact parts 131 d of the head 131 on both sides are incontact with the inside of the pair of rubber tubes 164. Since thedimension of the head 131 in the width direction on the front side islarger than the dimension in the width direction on the rear side,movement from the rubber tubes 164 to the rear side is regulated.

The coefficient of friction and the dimension R of the rubber tubes 164are set to such values that the shopper is capable of easily taking thehand scanner 130 from the scanner holder 160. Further, the coefficientof friction and the dimension R of the rubber tubes 164 are set to suchvalues that the hand scanner 130 does not come out of the scanner holder160 by vibration at the time when the shopping cart 10 travels.

Using the shopping cart 10 configured as described above, the shopperperforms shopping as follows. Specifically, the shopping cart 10 isinitially placed at the entrance or the like of a store. At this time,the hand scanner 130 is held by the scanner holder 160 of the shoppingcart 10 so that the handle 132 is directed below. The placement part 131c of the head 131 of the hand scanner 130 is placed on the supportingpart 161 c of the scanner holder 160. The pair of contact parts 131 d ofthe head 131 on both sides are respectively in contact with the pair ofrubber tubes 164 of the head regulators 162.

The shopper withdraws the shopping cart 10 in the stacking state in FIG.7 to be used. Further, the shopper takes a shopping basket placed in thestore, and places the shopping basket on at least one of the receptionpart 33 or the basket reception part 50 of the caster part 30. Then,while pushing the handle bar 42 of the shopping cart 10, the shoppermoves the shopping cart 10 toward a product shelf where products of thestore are displayed.

The shopper takes a target product from the product shelf. Further, theshopper takes the hand scanner 130 from the scanner holder 160. Theshopper brings the product code of the taken-out product close to thehead 131 of the hand scanner 130, and presses the scanner trigger 133.As a result, the product code is read by the hand scanner 130. Theinformation regarding the read product code is transmitted to thecontroller 154. The controller 154 displays the product name, the price,and the like on the display panel 152 on the basis of the informationregarding the product code. The shopper places the product whose productcode has been read by using the hand scanner 130 in the shopping basketplaced on any one of the reception part 33 or the basket reception part50 of the caster part 30.

In this way, after reading (scanning) the product code of the product byusing the hand scanner 130, while holding the handle 132, the shopperinserts the hand scanner 130 between the pair of arms 163 (headregulators 162) of the scanner holder 160 from above (upward in thevertical direction) so that the head 131 is directed upward (upward inthe vertical direction). In the handle 132, the maximum width H in thewidth direction is narrower than the dimension Q of the distance betweenthe rubber tubes 164 of the head regulators 162. Therefore, the shopperis capable of passing the handle 132 of the hand scanner 130 between thepair of rubber tubes 164. Therefore, the shopper is capable of placingthe head 131 on the supporting part 161 c of the scanner holder 160while holding the handle 132 of the hand scanner 130. Specifically,there is no need for the shopper to replace the handle 132 of the handscanner 130 with the head 131. The hand scanner 130 is held by thescanner holder 160 so that the handle 132 is directed below. At thistime, the placement part 131 c of the head 131 of the hand scanner 130is placed on the head support 161 (supporting part 161 c) of the scannerholder 160. When the head 131 of the hand scanner 130 is placed on thehead support 161, the head regulators 162 of the scanner holder 160 arein contact with the contact parts 131 d of the head 131 of the handscanner 130. The shopper pulls the hand scanner 130 upward from thescanner holder 160 and takes it when using the hand scanner 130. Then,after using the hand scanner 130, the shopper is capable of causing thehand scanner 130 to be stably held by the shopping cart 10, only byinserting the hand scanner 130 into the scanner holder 160 from above(upward in the vertical direction). Specifically, in the shopping cart10, the usability of the hand scanner 130 is excellent.

For example, the shopper moves the shopping cart 10 to move to the nextproduct shelf. At this time, vibration is generated in the up-and-downdirection (vertical direction), in the right and left direction (seconddirection), and the front-rear direction (first direction) in thescanner holder 160. Since the head 131 of the hand scanner 130 issupported by the head support 161 in the up-and-down direction (verticaldirection), it does not drop out of the scanner holder 160. Further,since the head 131 of the hand scanner 130 is held in the right and leftdirection (second direction) and the front-rear direction (firstdirection) by the head regulators 162, it does not drop out of thescanner holder 160.

When all the shopping is done, the shopper goes to a payment device.Then, the shopper performs an operation for payment of the shoppingproduct on the display panel 152 of the tablet terminal 150. Whenreceiving the operation for payment by the shopper via the display panel152, the controller 154 transmits a shopping list to the payment device.The shopper uses the payment device to make payment. The shopper who hasfinished the payment returns the shopping cart 10 to a predeterminedposition of the store.

In the case where the shopper stacks the shopping cart 10 for return, ifhe/she strongly pushes the shopping cart 10 into the forward shoppingcart 10, an upward (upward in the vertical direction) force from theforward shopping cart 10 is applied to the hand scanner 130. Further,similarly, in the case where a store clerk gathers and stacks the usedshopping carts 10, if he/she strongly pushes the shopping cart 10 intothe forward shopping cart 10, an upward (upward in the verticaldirection) force from the forward shopping cart 10 is applied to thehand scanner 130. The scanner holder 160 reduces the force of the handscanner 130 to jump out by the frictional force by the rubber tube 164,which makes it possible to prevent the hand scanner 130 from fallingoff.

As described above, according to this embodiment, even in the case wherethe hand scanner 130 receives vibration when the shopping cart 10travels or impact when stacking the shopping cart 10, the hand scanner130 does not easily come out of the scanner holder 160. Therefore, it ispossible to prevent the hand scanner 130 from being damages in advance,the shopper is capable of easily attach and detach the hand scanner 130,and the usability of the hand scanner 130 is improved.

Further, the head regulators 162 of the scanner holder 160 each includethe regulation arm 163 c formed to be directed below in the verticaldirection. Therefore, even in the case where an upward force in thevertical direction is applied to the head 131 of the hand scanner 130,the hand scanner 130 does not easily fall off. Further, the headregulators 162 each include the regulation arm 163 c formed to bedirected below in the vertical direction. Therefore, the head regulators162 do not easily fall off even in the case where an upward (upward inthe vertical direction) is applied to the head 131. Further, since therubber tubes 164 are attached to the regulation arms 163 c, frictionoccurs between the rubber tubes 164 with the contact parts 131 d of thehead 131. Therefore, even in the case where an upward (upward in thevertical direction) force is applied to the head 131, the hand scanner130 does not easily fall off and vibration applied to the head 131 isabsorbed.

The stopper 146 of the tablet case 140 is in contact with the frontsurface side (on the one side of the first direction) of the handle 132of the hand scanner 130 while the head 131 is held in the space of thehead regulators 162 (see, for example, FIG. 5). The stopper 146 is incontact with the front surface side of the handle 132 to regulate theforward (one side of the first direction) movement of the handle 132.Therefore, the position of the handle 132 is stabilized. Further, in anembodiment, the stopper 146 is formed of a member different from that ofthe lower end edge of the case body 141 of the tablet case 140.Meanwhile, by using the stopper 146 as the lower end edge of the tabletcase 140, the structure can be simplified without the need foradditional members.

Further, the tablet case 140 can be attached or moved to anothershopping cart that does not include the electrical device 100. Also inthis case, by the scanner holder 160 provided on the tablet case 140, itis possible to prevent the hand scanner 130 from falling off.

In the above-mentioned embodiment, in the tablet case 140, the positionof the attachment part 145 of the scanner holder 160 is on the left sideof the display panel 152, but may be on the right side of the displaypanel 152. Further, the scanner holder 160 may be attached at a positiondifferent from the tablet case 140. Further, instead of providing therubber tubes 164 of the head regulators 162, anti-slip processing may beperformed on the surface of the regulation arm 163 c.
